Washington State is one of the strictest online gambling jurisdictions in the US. Online gambling has been a Class C felony since 2006 (RCW 9.46.240) — up to 5 years imprisonment and $10,000 per violation. Sweepstakes casinos are specifically prohibited following Kater v. Churchill Downs (2018), where a Washington court ruled virtual casino chips are a "thing of value" making casino-style platforms illegal. Most major sweepstakes and DFS platforms block Washington residents. Although some platforms may appear technically accessible, participating in casino-style sweepstakes gaming in Washington violates state law. Social casinos with no prize redemptions are the only legally safe online gaming option.
Legal Gaming Options for Washington Residents
Social Casinos — Free-to-Play with No Prizes
Purely free-to-play social casinos — where players use virtual coins for entertainment only with no prize redemptions — represent the safest online gaming option for Washington residents. A small number of platforms allow Washington players in free-play mode only, with prize redemptions specifically blocked for WA users.
- Vegas World — Free slots, poker, and table games. No prizes, no cash redemptions.
- 7 Seas Casino — Free-to-play Vegas-style slots. No prizes, no purchase required.
- Casino World — A broad range of free social casino games.
Sports Betting at Tribal Casinos
In-person sports betting is available at licensed tribal casinos. Many tribal venues have launched sportsbook lounges in partnership with national operators (Caesars, BetMGM, DraftKings) — but their mobile apps only function when you are physically on tribal casino grounds (geofenced). Once you leave tribal property, the apps stop working. Sports betting from home or from non-tribal locations remains illegal.
Frequently Asked Questions
Are sweepstakes casinos legal in Washington State?
No. Washington State is one of the few US states that has specifically prohibited sweepstakes casinos. The landmark Kater v. Churchill Downs case (2018) established that virtual casino chips constitute a "thing of value" under Washington law (RCW 9.46.0285), making casino-style gaming illegal even when no real money is wagered. The Washington State Gambling Commission has confirmed that sweepstakes platforms offering casino-style games constitute unauthorized gambling. Most major operators — including Chumba Casino, WOW Vegas, McLuck, Global Poker, Stake.us, LuckyLand Slots, and Pulsz — block Washington residents from signing up or redeeming prizes. In June 2024, a Washington court declared High 5 Games' apps (social casino) illegal. A February 2025 jury awarded $25 million against High 5 Games in a class action lawsuit tied to its sweepstakes model.
Is online gambling illegal in Washington State?
Yes — Washington State made online gambling a Class C felony in 2006 under RCW 9.46.240 (Transmission of gambling information). Knowingly transmitting or receiving gambling information via the internet carries penalties of up to 5 years imprisonment and a $10,000 fine per offence. This applies to both operators and, theoretically, to individual players. Washington is one of the toughest online gambling states in the US — along with Utah, it is consistently cited as among the most hostile to online gaming.
Is sports betting legal in Washington State?
Yes, but only in-person at licensed tribal casinos. Governor Jay Inslee signed HB 2638 in March 2021, authorising tribal-exclusive sports betting. The first legal sports bets were taken at Snoqualmie Casino in December 2021. Each federally recognised tribe can apply to amend their gaming compact to offer sports betting. Mobile apps (DraftKings, BetMGM, Caesars) are available at many tribal venues, but they are geofenced — they only work when you are physically on tribal casino premises. Statewide mobile betting from home is illegal. Maverick Gaming, a cardroom operator, challenged tribal exclusivity in federal court; the 9th Circuit dismissed the challenge in March 2025, confirming tribal exclusivity under Washington law.
Are there casinos in Washington State?
Yes — Washington has 34 tribal casino venues operated by 29 federally recognised tribes, making it one of the largest tribal gaming markets in the US. Additionally, licensed commercial card rooms (not full casinos) operate statewide under Washington State Gambling Commission oversight. The largest tribal casino is Muckleshoot Casino Resort (Auburn), which completed a major expansion in January 2024 adding an 18-story hotel and expanded gaming floor with 3,500+ slots. Other notable properties include Tulalip Casino (Tulalip), Snoqualmie Casino (Snoqualmie), Angel of the Winds (Arlington), Emerald Queen Casino (Tacoma), and Northern Quest Casino (Airway Heights/Spokane).
Is daily fantasy sports (DFS) legal in Washington State?
No. The Washington State Gambling Commission has determined that paid fantasy sports contests constitute gambling under state law. All major DFS platforms — DraftKings, FanDuel, PrizePicks, Underdog Fantasy — block Washington residents. Using a VPN to circumvent this block violates both state law and platform terms of service.
What responsible gambling resources are available in Washington?
The Evergreen Council on Problem Gambling (ECPG) provides a helpline and treatment referrals at 1-800-547-6133 and ecpg.org. The National Problem Gambling Helpline is available at 1-800-522-4700, 24/7. The Washington State Gambling Commission runs a self-exclusion programme covering licensed card rooms; tribal casinos maintain their own self-exclusion programmes. Washington has no personal income tax — gambling winnings from tribal casinos are subject to federal tax only.
Washington State Gambling Laws
Washington gambling is regulated by the Washington State Gambling Commission (WSGC), a limited-jurisdiction law enforcement agency with five commissioners and four ex-officio members. The WSGC licences and oversees commercial card rooms, charitable gaming, and state-level gambling activities, and coordinates with tribes on Class III gaming compact oversight. Tribal gaming (including the 34 tribal casinos) is separately regulated under federal-state tribal gaming compacts.
Washington's gambling framework is built on a simple principle: if an activity is not specifically authorised, it is prohibited. This inverts the typical US legal approach (where activities are legal unless specifically banned). The result is one of the most restrictive gambling regimes in the country.
Key statutes: RCW 9.46.240 (internet gambling Class C felony, 2006); RCW 9.46.0285 (broad "thing of value" definition covering virtual tokens); RCW 9.46.0356 (narrow promotional sweepstakes carve-out, which courts have found does not extend to casino-style gaming platforms).
Kater v. Churchill Downs — the case that shut out sweepstakes casinos
In 2018, a Washington court ruled in Kater v. Churchill Downs that virtual chips purchased at Big Fish Casino (a social casino app operated by Churchill Downs Inc.) constituted a "thing of value" under Washington's broad gambling statute. This meant that Big Fish Casino was operating an illegal gambling game. The ruling was significant nationally because Big Fish Casino used a virtual currency model similar to sweepstakes casinos — players purchased chips that had no direct cash value but extended gameplay. Washington courts applied the state's broad "thing of value" definition to include credits, tokens, and "the privilege of extended gameplay." The case resulted in a $155 million class action settlement and effectively established that Washington will not accept the sweepstakes model as distinct from gambling. The June 2024 High 5 Games ruling and the February 2025 $25 million jury verdict against High 5 Games extended this precedent.
Washington State Gambling History
Washington's tribal gaming history predates the Indian Gaming Regulatory Act — the Puyallup Tribe opened what may have been the first tribal casino in the US in 1976, though it was subsequently ordered closed by the federal government. After IGRA passed in 1988, Washington's many federally recognised tribes negotiated gaming compacts, and tribal casinos proliferated through the 1990s. Washington now has 34 tribal casino venues — one of the densest tribal gaming networks in the US.
The Washington State Lottery launched in 1982. Licensed card rooms have operated under WSGC oversight since the 1970s. In 2006, Washington took the unusual step of enacting RCW 9.46.240, making internet gambling a Class C felony — one of the harshest online gambling statutes in the country. Sports betting was authorised via tribal compacts in 2021, with the first bets accepted at Snoqualmie Casino in December 2021.
